"Try this" support #
This implements a mechanism for tactics to print a message saying Try this: <suggestion>
,
where <suggestion>
is a link to a replacement tactic. Users can either click on the link
in the suggestion (provided by a widget), or use a code action which applies the suggestion.
This is a widget which is placed by TryThis.addSuggestion
; it says Try this: <replacement>
where <replacement>
is a link which will perform the replacement.
